Williams and Mercedes-Benz have confirmed the agreement of a long-term engine partnership from the 2014 Formula One World Championship season onwards.

Under the terms of the widely anticipated agreement, Williams will be supplied with a Mercedes-Benz engine and recovery system by Mercedes AMG High Performance Powertrains in Brixworth. Williams will continue to manufacture its own transmission.

Speaking about the new partnership, Frank Williams said: "I'm delighted to announce our new association with Mercedes-Benz for the 2014 Formula One season and beyond. Mercedes-Benz has been one of the sport's most successful engine suppliers and we believe that they will have an extremely competitive engine package. I would also like to take this opportunity to thank Renault for their continued hard work since we renewed our engine partnership at the beginning of the 2012 season. We have enjoyed a strong relationship that has resulted in much success over the years, including powering us to winning ways once again last year at the Spanish Grand Prix."

"The announcement of this partnership is exciting news for Williams," added Deputy Team Principal, Claire Williams. "Securing the right engine supply partnership is a key milestone in the implementation of our strategy for long term success. We are also pleased to conclude this agreement early in the season and we very much look forward to working with Mercedes AMG HPP in developing our 2014 race car."

It is a very proud moment for everybody at Mercedes AMG High Performance Powertrains to announce the start of this new partnership with the Williams F1 Team," said Andy Cowell, Managing Director of Mercedes AMG HPP. "Williams is one of the sport's iconic names and we are very excited to be working together towards a successful future under the new regulations. A further positive is that this new agreement provides Mercedes-Benz with the long-term stability of supplying our works team and at least two partners from the 2015 season onwards, following the conclusion of our relationship with McLaren at the end of next season."

"The proud heritage of Williams and the company's commitment to technological excellence make it a perfect long-term partner for Mercedes-Benz under the new powertrain regulations," concluded Toto Wolff, Executive Director of Mercedes AMG Petronas. "It is a win-win situation for both HPP and Williams, which will ensure HPP is able to supply at least three teams on a long-term basis under the new regulations and could open interesting new perspectives for technology transfer. We look forward to enjoying much success together over the coming years."
